Enable Quota limit across reboots.

Hi,

Just few clarifications.

Quota (both hard and soft) limits has been established for users. But gets disabled after reboot. After going through man page for quota(5), found out that quota option needs to be entered against FS to enable quota across reboots. Is this true, I mean have I understood it right? Did anyone had to do this? And, should the entry be made manually (using vi on /etc/fstab) or any command with options?
